The biggest problem I have with the 5970's is that upon reboot you have to return the cards to stock clocks in CCC or the miners will freeze the system when they start if its overclocked at all. This is a real pain. I wish there were a way I could through a startup process force the cards back to stock clocks on reboot. Another issue is that whenever I change the clock speed in MSI Afterburner the Fan control in CCC goes to auto and the fans do not go fast enough in auto. So I have to go and manually set them at 100% or whatever, if the system is reacting slowly or im not quick enough the system will lockup due to overheat. Kind of a pain. Any suggestions?
